CRANKCASE VENTILATION PIPE
When the engine is working, the high-pressure combustible mixture and burned gas in the combustion chamber will more or less leak into the crankcase through the gap between the piston group and the cylinder, causing blow-by.
To prevent the crankcase pressure from being too high, extend the oil life, reduce parts wear and corrosion, and prevent engine oil leakage, crankcase ventilation must be implemented.
In addition, to meet increasingly stringent emission requirements and improve economy, the crankcase ventilation system must also be designed during the design of automobile engines.
